REGULATOR FOR WATER-HEATERS.

1,115,466. Specification of Application filed March 20,

To all whom it may concern Be it known that I, lVILLIAM HORRQQKs, a citizen of the United States, residing at Herkimer, in the county of Herkimer and State of New York, have invented a new and useful Improvement in Regulators for Water-Heaters,-.of which the following is a specification.

This" invention relates to regulators for water heaters and is primarily intended for incubators, for automatically regulating the temperature of the incubator. The invention is, however, also applicable to Water heaters for other purposes.

The object. of the invention is to produce a practical and efiicient automatic regulator sensitive in action and operate so as to maintain a practicallyinvariable temperature of the Water. This is accomplished by mounttank or receptacle which is connected to the water circulating system so that the exuct-uations in the temperaturethereof, will cause'an increase .or decrease in the amount and weight of the water inthe expansion tank and thus move the balance beam which is connected to the regulating dampers of the-fwater heater.- It has been attempted expansion and contraction of 'the.water in a receptacle connected with the water C1IV culating system. In suclr an arrangement,

thewater necessary to produce a substantial movement of the float and regulating action water therein, as, above explained, a very slight change in the amount of water in the stantial movement of the lever and thus In the accompanying dra'wing'zFigure, 1

Vention. Fig. 2 is a'fraginentary side elevation thereof. Fig-3 is .a'plan view of the Letters Patent. Patented Oct. 27, 1914.

heater, on'an enlarged scale. Fig. 4 is a different position of the regulating mccha nism.

Like reference characters refer to like parts in the several figures. v

A represents a Water heater of ordinary construction having a draftdampcr a, a damper at which controls communication between the tire pot and the smoke pipe, and a check damper (Z for admitting air to the smoke pipe.

b and '6" represent respectively the outgoing and return pipes of the Water circula'ting system, Which,-in thc apparatus shown in the drawings, in an incubator C. Y

D represents a tank or receptacle which is movahly supported on a pivoted balance beam or lever E and is connected. by a pipe ml with some part of the Water circulating includes a heating coil 0 system of the heater, for instance, to the return pipe Z) thereof, so that the expansion and contraction of the water in the system, due to changes its temperature, will cause the Water to rise'or fall more or less in the expansion tank D and therefore increase or decrease the weight on the tank end-oat the beam or lever -E accordingly. The pipe d has a section (1 of flexible hose, or it is otherwise connected to theexpansion tank D'so as to permit the tank to movewith the beam or lever E1 The beam or leveris preferably-secured to a shaft 6 which is mounted to rock in a bearing framee' of ,any suitable construction on the heater A and isprovided with rigidly secured arms F G and H. The arms F and G'extend in the same direction from the shaft, preferably at its opposite ends; and the former is connected byachain'f or the like to'the'draft damper a, while the latter is connected b nection to the smoke pipe damper'a. The third arm H is preferably integral with the arm G and extends in the opposite direction from the rock shaft, being connected by a' chain it to the check damper a A weight I a rod 9 or other (1011*,

isadjiistably secured on the balance beam 'a'tthe/opposite side of the shaft, from the.

expansion tank. By appropriately adjust:

anced so that it will be caused to s, \,i'-In'g in -one or the otlrr direction bypa'shght inving this weight the beam can be nicely balv crease or decree'se in the Weight'of Water in the-expansion tanls- V In; the operation of the regulator, if the telhperdtfire of the Writer falls below a pre-' determined desired vmiei'mum, the conse- .uent contract-ion ofwthe water will lower t e level thereof iii-the expansion tank andthe tanls-eridof thebelance'beam will rise, whieh'. will open the draft and smoke pipe dampers (lend 6 and clqse'the check dainper a This will cause a hotter fire in the heater and arise in temperature of the We tor." The waterz will expand as its tempera I tur rises,-and raise the water level in theexpansion tank'whi'ch will cause thetenk' f-enclf'of the "lever to descend, thereby clos -'ing theid'r aft and smoke 'pipe dampers a and a and opening thegcheek dampes a, whieh again reduces the temperature of the water. 'The heam will thus oscillate st nt} as.

, tuate the dampers in response to fluctuations in. the temperature of the waiter so! as to maintain s'gpracticall constant predetev fmined temperature '0 the water. the mechanism described is susceptible of beingnicely balanced, it will. be. evident that it cim ,be. caused to f o erate u on a very Y slight change. in the'wvelght of t e water in the expansion tank. The regl llatoris therefore very sensitive in" action, and a, smell chahge. in the weight of the Water in the expansion tank-will produce a substantial movement. of the balance beam and the (l ampersof the heeter.
